BMW’s M3 and M4 photos leak ahead of Detroit debut

Photos of BMW’s latest M3 sedan and M4 coupe have surfaced online weeks before their intended debut at next month’s Detroit Auto Show.

The overhauled vehicles feature a sportier exterior and upgraded interior detailing. The leaked option sheets also show that adaptive suspension, 19-inch wheels, and heads-up display will be available to complement the usual options of heated seats, LED lighting, and side and rear cameras.
